Use new libosmocore logging lock API

Since libosmocore Id7711893b34263baacac6caf4d489467053131bb, a new API
log_enable_multithread() is available which takes care of protecting
logging infrastructure from us (and actually does it correctly since we
cannot protect internal libosmocore structures from osmo-trx).

Let's drop all mutex related code from osmo-trx logging infra and simply
rely on libosmocore's.
